EAGLES If the recent “History of the Eagles” documentary illuminated the reality that things weren’t always harmonious with the classic rock band offstage, it reminded viewers just how harmonious it can be when the members raise their voices together in song. An added bonus to the current tour: original member Bernie Leadon will be joining Don Henley, Glenn Frey, Joe Walsh, and Timothy B. Schmit, which we hope means the group will be dipping a little deeper into its back catalog. July 19, 8 p.m. Tickets: $50-$235. Comcast Center. 800-745-3000, www.livenation.com

JUSTIN BIEBER Although lately the Beebs has been making more noise with tabloid headlines — Is he or isn’t he reuniting with Selena Gomez? Did he really just urinate in that mop bucket? — than pop songs, the focus should fall squarely on the Canadian teen heartthrob’s hits during this return trip to the Hub to support “Believe.” July 20, 7 p.m. Tickets: $42.50-$92.50. TD Garden. 800-745-3000, www.ticketmaster.comSARAH RODMAN
